5:20 PM Workout. HR ??-133. 121? average HR. 2:28.3 average split. 25-28 SPM. Did 2K to start, but HR belt did not work. Stopped to reset belt. Started 10K again without HR belt working properly. It kicked in at 4K to go. The piece was going really well, but I had to slow down because there was a pull of sorts inside my left thigh. After taking it down I was able to get back into doing the work to finish with a really good 3.5K to go.
